Objective To study the current situation of diagnosis and treatment of rudimentary uterine horn pregnancy through 4-cases report. Methods We made a clinical study of 4 cases of rudimentary uterine horn pregnancy admitted to our hospital between 1995 and 2005. Results Three patients had been undergone artificial abortion before they were admitted to our hospital. All the patients were asymptomatic. Ultrasonography was made in 3 cases. Two cases were diagnosed as rudimentary uterine horn pregnancy. Three patients were cured with surgery. Conclusions Rudimentary uterine horn pregnancy is rare and with atypical clinical manifestation in the first trimester. Although diagnosis before surgery is difficult, ultrasonography and MRI make a great role. Surgery is the most important therapeutic method.

Objective To investigate interleukin 10 (IL 10,Th2 type cytokines) and interferon gamma (IFN ?,Th1 type cytokines) secreting capacity by peripheral blood mononuclear cells (PBMCs) in 30 patients with systemic lupus erythematousus (SLE) and 10 healthy individuals,and try to understand the role of Th1/Th2 balance in the pathogenesis of SLE.Method Sandwich ELISA was used to measure IL 10 and IFN ? level in the supernatant of culture from PBMCs.Results The level of IL 10 produced spontaneously by PBMCs in active stage was significantly higher than in static phase and healthy person ( P 0 05).Conclusion These data suggest that the Th2 type cytokine (IL 10) was increased in patients with SLE,and an imbalance towards Th2 predominance may play a significant role in the pathogenesis of SLE.Regulating IL 10 level may provide a new approach for the treatment of SLE.

Objective To investigate the effects of azithromycin on hyperoxia induced lung injury in neonatal rats.Methods Ninety 2-day-old neonatal rats were randomly divided into 3 groups (30 cases in each group):air control group,hyperoxia model group,azithromycin treated group.The rats in air control group were exposed to indoor air,and the rats in hyperoxia model group and azithromycin group were exposed to 900 mL?L-1 O2 for 14 days.From 2-days-after birth,rats in treated group received intraperitoneal injection of azithromycin (200 mg?kg-1)per day,rats in air control group and hyperoxia model group received intraperitoneal injection of normal saline.Ten rats in each group were executed and their lung tissues were taken out and were observed under a optical microscope on the 3rd,7th,14th days from the start.The expression of interferon gamma(IFN-?),connective tissue growth factor(CTGF) and matrix metalloproteinase-9 (MMP-9) in the lung tissues were detected by immunohistochemistry.Results There was no expression of IFN-? positive cells in air control group,but the expressional intensity level was gradually enhanced as the time of inhaling hyperoxia prolonged in hyperoxia model group,it reached the peak on the 7th day,and then obviously declined on the 14th day,but still higher than that of air control group.The expressional intensity level of IFN-? in azithromycin treated group was lower than that of hyperoxia model group in each time segment,there were significant differences among them(Pa

Objective To study effects of Shoucong capsule on the learning-memorial ability,CAT and MAO activities in brain tissue of AD rat.Methods Male Wistar rats were randomly divided into 5 group:blank compared group,model compared group,Naofukang group and Shoucong capsule(low,high dose) group,every group contained 9 rats.They were injected with D-galactose into the neck and injected with scopolamine into the intraperiton to making AD compound model rats.The learning-memorial ability were examined by diving-stand test,and CAT and MAO activities in brain tissue were determined by spectrophotometry.Results Shoucong capsule greatly deceased error time and enhanced the electric latent period,and enhanced the activities of CAT while deceased the activities of MAO in model rats.Conclusions Shoucong capsule has significantly effect of preventing and treating senile dementia in AD rats by enhancing the activities of CAT and deceasing the activities of MAO in brain tissue.

Objective:To explore the urgent management strategy for quadriplegia following China Wenchuan earthquake under filed condition.Methods:The 57-year-old male patient was sent to the earthquake relief team of Changzheng Hospital,Second Military Medical University.He was hit by heavy object during the Sichuan earthquake 6 days ago.Physical examination revealed cervical spinal cord injury accompanied by incomplete paralysis.The patient underwent cervical 3-7 laminectomy under general anesthesia.Results: After surgery,the muscle strength of lower limbs recovered to grade four from grade one;the muscle strength of upper limbs recovered to grade five from grade three.Sensory loss was found below the nipple level and totally recovered after operation.Conclusion:Early surgery for quadriplegia following earthquake trauma can timely relieve compression to the spinal cord and therefore improve prognosis of patients.Under field condition where facilities are not readily available,decompression of spinal cord can be achieved by lamineetomy via posterior approach.The key to successful operation is correct diagnosis and skillful manipulation.

OBJECTIVETo compare the clinical therapeutic effects on intractable facial paralysis among acupuncture, acupoint catgut embedding and PDS embedding.

METHODSTwo hundred and seventy-nine patients of intractable facial paralysis were randomized into an acupuncture group, a catgut embedding group and a PDS embedding group, 93 cases in each one. Cuanzhu (BL 2), Yuyao (EX-HN 4), Taiyang (EX-HN 5), Xuanlu (GB 5), Dicang (ST 4), Jiache (ST 6), Quanliao (SI 18), Qianzheng (Extra), Xiaguan (ST 7) and Fengchi (GB 20) on the affected side and bilateral Hegu (LI 4) and Zusanli (ST 36) were selected in the three groups. In the acupuncture group, acupuncture was applied to those acupoints, once every two days; 10 treatments made one session; the successive three sessions were required. In the catgut embedding group and the PDS embedding group, catgut and PDS were embedded separately, once every 10 days; 3 treatments made one session and the successive two sessions were required. The therapeutic cycle was 2 months in the three groups. The therapeutic results were analyzed statistically 2 months later. The scores of Sunnybrook facial nerve grading system and the facial nerve electroneurography (ENoG) were used for the efficacy assessment before and after treatment in the three groups.

RESULTSAfter treatment, the score of Sunnybrook facial nerve grading system was improved apparently after treatment as compared with that before treatment in any of the three groups (all P < 0.05). The score in either of the embedding groups was better than that in the acupuncture group (both P < 0.05). The difference was not significant between the catgut embedding group and the PDS embedding group (P > 0.05). After treatment, ENoG wave ampli tude values in the frontal muscle and orbicularisoris muscle on the affected side were improved as compared with those before treatment in the three groups (all P < 0.05). Those in the catgut embedding group and the PDS embedding group were better than those in the acupuncture group (all P < 0.05), and had no significant difference as compared with those on the healthy side (P > 0.05). In the acupuncture group, ENoG wave amplitudes on the affected side were lower than those on the healthy side (both P < 0.05).

CONCLUSIONAcupuncture, catgut embedding and PDS embedding at acupoints all achieve the therapeutic effects on intractable facial paralysis. However, the acupoint embedding therapy presents more advantages on the recovery of facial nerve function. The efficacy is similar between the catgut embedding and the PDS embedding.
